Abstract: Five patients with mediastinal bronchogenic cyst (MBC) were treated with endoscopic submucosal tunnel dissection (ESTD) between January 2018 and October 2019 at the Department of Gastroenterology in Henan Provincial People′s Hospital. Lesions were located in the middle or lower esophageal level, with diameters≤3.5 cm. The tunnel establishment time was 13-18 min, and the tumor stripping time was 30-51 min. The number of titanium clips used for tunnel closure was 5-8. The tumors were completely resected. No major bleeding or hypoxemia occurred during the operation and no serious adverse reactions occurred after the operation. Postoperative pain scores were all ≤3. The hospital stay was 4-7 days. There was no tumor residue and recurrence during 4-23 months of follow-up.It is suggested that ESTD for MBC which derived from post mediastinum and located at the lower or middle level esophagus is safe and effective.
